The "randomness" of the order has to do with which file system is in 
use/needs something expired.  So, if MythTV records to a file system 
that only has shows recorded this week on it and another file system has 
shows recorded 7 years ago, it will expire something from this 
week--because, well, expiring one of those shows from 7 years ago won't 
help us fit /this/ recording on /this/ file system.

Again, though, in all my time with MythTV (since Feb 2004), there has 
never been (TTBOMK) a case where "the autoexpirer went crazy".  Its 
failure mode has always been to stop expiring things when they needed 
expiring (which usually results in a file system filling up).  If 
someone has information on a case where that's not true, I'd love to see it.
